JAKOB CORZILIUS, OF PATERSON, NEIV JERSEY.

PlLE-FABRIC L'OOM.

SPECIFICATION forming part of Letters Patent No. 522,931, dated July 10,1894.

Application filed September 16, 1893. Serial No. 485,703. (No model.)

To all whom it may concern:

Be it known that I, JAKOB CORZILIUS, a subject of the Emperor ofGermany, and a resident of Paterson, in the county of Passaic and Stateof New Jersey, have invented certain new and useful Improvements inPile- Fabric Looms, of which the following is a specification.

This invention relates to improvements in pile-fabric looms, andespecially to that class of such looms in which two pieces of pilefabrics are woven at the same time and are separated by a knife whichcuts the pile threads,

so as to form two pieces.

The object of my invention is to provide a device for automaticallysharpening the knife while the same travels to and fro.

The invention consists in the combination with the weaving parts of aloom, of a suitable track, a carriage mounted on the same, a rotaryknife mounted on the carriage, holders for abrading stones hinged on thecarriage, springs acting on said holders to press the stones in contactwith the rotary knife and means for rotating the knife.

The invention also consists in the construction and combination of partsand details,

which will befully described hereinafter and finally pointed out in theclaim.

In the accompanying drawings, Figure 1 is a front elevation of myimproved loom, with the cutting attachment, parts being broken out. Fig.2 is a horizontal sectional view, on the line 2 2, Fig. 1. Fig. 3 is avertical trans- Verse sectional view, on the line 3 3, Fig. 2. Fig. 4 isan enlarged detail plan-view of the cutting attachment, and Fig. 5 is alongitudinal vertical sectional view of the same on the line 5 5, ofFig. 4.

Similar letters of reference indicate corresponding parts.

The circular cutting blade or dish A is mounted with a slightinclination on the traveling carriage B, which is provided in its underside with a headed tenon O that travels in a longitudinal groove Dformed in the top of a rail Dfastened in the loom frame between the twoguide rollers a b for the two pieces of plush fabric f.

The ends of a wire or cord E are fastened to opposite ends of the tenon0, run along the groove D and at the ends of the rail D pass overpulleys F in the frame of the loom and then are passed several timesaround the large pulley G fixed on a shaft G journaled on the top of theloom frame, which shaft G also carries a smaller pulley G The wire orcord E then passes over a pulley F. at the opposite side of the loomframe and overa pulley F at the end of the rail D.

A strap H passes over the pulley G and its ends are secured to twotreadles I, which are operated by tappets J driven by means of the bevelgearing K from the driving gearing of the loom.

The cutting disk carries on its top a pinion L that engages a rack Marranged above the rail D and extending over part of the rotatingcutting disk.

The carriage is provided on its rear edge with a standard N carrying ashaft 0, on which are mounted two swinging supports P for whet-stones Por like abrading devices. The holders P are provided with flanges toform sockets, into which the ends of the whet-stones can he slipped. Thepockets P are so arranged'that one is on the upper surface of the rotarycutting disk and the other below the same. Suitable springs Q act on thesaid pockets orholders Pand press the whet-stones in the same againstthe surface of the knife.

As the loom is operated the bevel gearing K is also operated, and bymeans of the tappets J alternately depresses the two pedals I. Therebythe pulley G is alternately rocked in one direction or the other andthus the carriage B is moved from right to left, then from left toright, and so on. As the carriage moves in this manner the knife isrotated by the co-aetion of the rack M and pinionLand cuts the pilethreads uniting the two layers of fabrics, thus forming the two separatepieces of plush d f or like fabric. As the knife rotates it isconstantly sharpened by the abrading stones, of which one rests on theupper and the other on the lower surface of the knife.

Having thus described my invention, I claim as new and desire to. secureby Letters Patent- The combination with acarriage and means for guidingand reciprocating the same, of a circular knife mounted to rotate onsaid carriage, a pinion connected with said circular knife, a fixed.rack: engaging said pinion, two my invention I have signed my name inpreswhetstone holders hinged to the carriage, one enee of twosubscribing witnesses. above and the other below the knife, and

springs acting on said Whetstone holders to JAKOB CORZILIUS' 5 press thewhet-st0nes in the same in contact Witnesses:

with the knife substantially as set forth. PE TER KoRzILIUs,

In testimony that I claim the foregoing as JACOB SMETS.
